🧠 Skills with TypeSafe Jev Integration
Four skills now support optional integration with TypeSafe Jev — a judgment engine that provides calibrated probability assessments (Score) and categorical classifications (Noul) for subjective evaluation criteria. When Jev is available, these skills use it for nuanced quality judgments; when unavailable, they fall back to heuristic methods.
| Skill | Jev Use Case | Questions |
|---|---|---|
| humanizar | Pattern severity, voice match quality, rewrite confidence | 8 Score + 12 Noul |
| human-ai | Pattern severity, voice match quality, rewrite confidence | 8 Score + 12 Noul |
| slop-eval | Tell severity, axis quality, section classification | 8 Score + 16 Noul |
| agent-plugin-eval | UX coherence, documentation clarity, schema design, secret detection | 7 Score + 19 Noul |
Each skill includes:
scripts/jev_questions.json— question definitions with context requirementsreferences/jev-integration.md— integration patterns and code examples- Discovery protocol in SKILL.md — check

💡 Startup Idea 
· data-fetching-and-analysis
Analyzes a startup idea through three lenses at once: Paul Graham (pressure test, founder-market fit, brutal validation), Dan Koe (monetization, offer, distribution, sales) and Seth Godin (differentiation, narrative, smallest viable audience). Delivers a pressure test, a monetization path, the minimum viable audience, a remarkability check and an action plan — not a generic canvas.
When to use: validate a startup idea, pressure-test a business model, define the MVP, find the first customers, design the revenue model, plan go-to-market, chase product-market fit, or any variation of "I have an idea".
